While trying to come along with VIM I accidently lowered my font size of one of my windows in ´i3´. I could not find the proper shortcut to do so via google. Can somebody tell me how to change font size via shortcuts within a window in ´i3´?

    It hardly relates to i3 itself, but rather to the app in the window. Is that terminal or gui app? Anyway Ctrl-+ is most common shortcut to increase font size in many apps, so it worth trying that

Most probably, that is not i3 specific question. Many applications provide following shortcuts to handle font size:

Ctrl - +  increase
Ctrl - -  decrease
Ctrl - 0  reset

(could not figure out how to make pretty-looking button-shaped shortcuts)
